Application filed January 19, 1918. Serial No. 212,754.

To all whom t may concern:

Be it known that I, BENJAMIN B. Bn'r'rs, a citizen of the United States,and resident of St. Louis, State of Missouri, have invented new anduseful Improvements in Railway-Frogs, of which the following is aspecification containing a full, clear, and exact description, referencebeing had to the accom anying drawings, forming a part thereof.

My invention relates to certain new and useful improvements in railwayfrogs which has for its special object the employment of a pivoted frogpoint, which is controlled in its movement b a guard lever or tongue,which is operate by the movement of the rolling stock.

In the drawings,

Figure 1 is a top plan view of my invention.

Fig. 2 is a bottom plan view of the same.

Fig. 3 is an A'end View looking in the direction of the arrow 3 in Fig.1.

Fig. 4 is a longitudinal section taken on a line 4-4 of Fig. 3 lookingin the direction of the arrow.

Fig. 5 is a bottom plan view of the pivoted frog point.

Fig. 6 is a longitudinal section of the same taken on a line 6-6 of Fig.5.

Fig. 7 is a transverse section taken on a line 7--7 of Fig. 5 looking inthe direction of the arrow.

Fig. 8 is atop plan view showing a slightly modified form of myinvention.

Fig. 9 is a bottom plan view of a pivoted controlling guard lever ortongue for operating the frog point.

F 1g. 10 is a top plan View of a modled form of my invention showing thesame built up out of pressed steel.

Fig. 11 is a bottom plan view of the housv ing which carries the guardand lever mechan1sm.

Fig. 12 is a sectional view looking 1n the direction of arrow taken on aline 12-12 of Fig. 10.

Fig. 13 is a bottom plan view of the frog point which I employ in themodified form of my invention.

Fig. 14 is a side elevation of the same, and Fi 15 is a section taken ona line 15-15 of Flg. 1, looking in the direction of the arrow.

Referring to the drawings, Fig. 1, which shows my invention cast 1n onepiece, 16 indicates what might be termed a base plate, which is providedthroughout with a series of spike openings 17. Cast integral with thebase plate 16 is an elevated plate or portion 18, and formed integralwith the plate 18 are guards 19, located at one end of the frog, andlocated at the other end are continuations 20 of the rail ends 21.

Formed on the opposite end of the frog are the rail ends 22. To the railends 22 and 21 rails may be secured by iisli plates in the ordinarymanner.

23 indicates the movable pivoted frog point provided on one end with astud 24 which is mounted in a suitable `opening 25, formed in theelevated seat 18 and is secured therein by means of a cotter in 26.

Secured intermediate of tie ends of the frog point 23 is an integralstud 27 which is mounted in an elongated opening or slot 28,formed inthe elevated seat 18 and rojects downwardly through the same. gutwardlyprojecting on each side of the stud 27 is a cover plate or flange 29awhich is adapted to cover the opening 28 to prevent the access of dirt,snow or any foreign substance into the opening 28 and thereby interferewith the operation of the frog point.

The forward end of the frog point 23 is provided with recesses orpockets 30 for the accumulation of any substance that might be lodgedaround the end of the frog point or in its seats.

As shown in Fig. 1 the frog point is rounded at 31 so as to fit therounded recess or depression 32 formed in the rail extensions 20.Mounted between the rail extensions 20 is a guard point or tongue 33,which has secured to its under surface a stud 34 which is mounted in anopening 35 of the elevated seat 18 and is also provided with another'stud 36 mounted in an elongated opening 37. The stud 34 is secured inplace by means of a cotter pin 38. Mounted on the stud 36 and secured`thereto by means of a Cotter pin 39 is one end of a lever 40, saidlever being mounted on a stud or bearing 41 and secured thereon by meansof a Cotter pin 42. The opposite end of the lever 40 is pivotallymounted on the stud 27 of the frog point 23. The lever 40 forms aconnection between the frog point 23 and atethefrog point in theopposite direction,

the guardlever or tongue 33 whereby the movement of either one willtransmit motion through said lever to the other in the opositedirection; that is to say, if the lever 33 is operated in one directionby the flange of the car wheels such movement will oper` the ends of therail extensions 20 andthe guards 19, however, if desired this space maybe filled out by a guard`43 connecting the same as illustrated in Fig.8.

In Figs. 1, 2, 4 and 8 I have shown theV frog cast integral.` When somade it is of a hollow formation and is provided with strengthening ribs44. j 'Y In Figs. 10 and 11.1 have shown my improved frog made ofpressed steel, in which construction I use a base plate 45 and a topplate or housing 46. These two may be riveted together or fastenedtogether by means of spikes passing through the spike openings 47 and48.

the guards 19 are rivetedl to thevhousing as well as the rail extensions20 and 22. This construction is practically the same as whenV 1. Arailway frog comprising a base, a

frog point pivotally mounted on lthe top thereof, guards carriedby thebase and dis- Y posed on each side of the frog point adjacent itsconnection to the base, a guard lever pivotally secured to said base, aguard secured to said base on` each side of said guard lever, saidguards being provided with seats to receive the end of the frogpointVwhen thrown inoperative position, and a lever connection between thefrog point and guard lever whereby the operation of one in a givendirection will cause the other to l be operated in an oppositedirection.

2. A railway frogV comprising' a base plate, a housing secured thereto,a'pivoted frog point mounted on the housing, guards mounted on each sideof the frog point adjacent its point of pivotal connection, a guardlever carried by the frog, a guard and rail extension mounted on eachside of the guard lever and .provided with a seat to receive Athe end ofthe frog point, a lever connection Abetween the frog point and guardlever whereby, when the frog point is moved in one direction, the guardlever will be. thrown in the opposite direction and vice versa.

3. A railway frog comprising a base'plate provided with an elevated seatandl spike openings, rail ends secured to the frog at one end, rail endsand rail extensionsprovided with seats for theV frog point securedtotheopposite end of the frog, guards carried by the frog adjacent one endthereof, a' pivoted frog point located between the guards, av

pivoted guard tongue or lever mounted between the rail extensions, and aconnection between the frog point and guard tongue whereby the movementof one will cause theV other to move in theopposite direction. Y

4. A railway frog comprising a base or support, rail ends' carried byone endofthe base, guards carried by said end ofthe base, a pivoted frogpoint having one end pivoted between the guards, rail sections i Ycarried by the opposite end of the base pro- When my frog is made out ofpressed steel vided in their inner' erids with va recess in which the'free end of thefrog Apoint is adapted to be seated, a guard' toiigueorlever pivoted between the rail sections, and` a lever pivoted to `thebaseand having `one` end pivoted to the frog point and itsvopposite endpivoted to the guard lever whereby'upon the' operation of eitherthefrog' point or guard lever the other will be'o'perated'in theopposite direction.

5. In a railway frog', a pivoted frogpoint, guards positioned on eachside of said frog point adjacent its pivoted end, the said frog pointVbeing provided on its free end with recesses, a guard lever adapted tobe operated by the movement of the wheel; flange,

and aV connection between said frog point and lever whereby thevoperationA of one will cause the other to be operated in the oppositedirection. f

Y 6. In a railway frog, .a cast frogpoint provided at one end with apivotv stud; and

t intermediate its ends with a studjandV intermedi'ate of its ends withtransverse ribs. Y

7. In a railway frog, a cast 'frog `point provided with a pivot stud anda stud spaced apart from the pivot" stud, and on'each side of its sidesadjacent said last mentioned stud, with a lateral flange. i

8, A railway frog comprising, a base plate, a pivoted Vfrog pointmounted thereon, rail sections secured to the frog 'and adjacent saidfrog point, a guard secured'on each side of said frog point, rail endsand rail extensions secured to the opposite end of the frog, a guardlever pivoted between said rail extensions, the said rail extensions andfirst mentioned guards being spaced apart and the said frog pointspanning the space between tbe rail ends and rail extensions andanswering as a running rail between the two, and a connection betweenthe end of the frog point and base for limiting the lateral 10 throw ofthe same.

In testimony whereof I have signed my naine to this specification inpresence of tWo subscribing witnesses.
